Claims

[Scope of utility model registration request]

A refrigeration cycle circuit consists of a compressor, a four-way valve with an internal slide valve, an indoor heat exchanger, a receiver tank, and an outdoor heat exchanger, and the slide valve of the four-way valve is controlled by a control valve. In a heat pump type air conditioner that performs cooling/warming switching operation based on the high/low differential pressure of the cycle, the receiver tank is provided with a liquid groove outlet for taking out the condensed liquid, and the liquid groove outlet is connected to the liquid groove outlet through the side control valve. A heat pump type air conditioner characterized in that the piston chamber of the four-way valve is connected to the piston chamber of the four-way valve.
